Hi everyone, I'm Hà Serious.
Wasps are one of the most dangerous insects in the world.
Due to their aggressive nature, large size, dangerous venom, they are not only dangerous to humans
but also show their unrivaled strength when fighting other insects.
Let's find out their battles together.
1. Asian giant hornets attack honeybees:
The Asian giant hornet is the largest species of wasps in the world.
Their body length can be up to 5.5 cm long.
These wasps are invading a honeybee nest, their purpose is to steal honey and larvae.
With its enormous size, extremely strong jaw and strong venom, a hornet can kill a honeybee easily.
A wasp can kill a lot of honeybee in a short time.
Honeybees also gather to fight back, but their weapons are too weak compared to wasps.
If they inject venom into the body of the wasps, they will die themselves,
, because this bee can only inject once in their lifetime,
after the injection, the needle will lie on the body of the wasp.
Honeybees will have to sacrifice many members just to kill a wasp.
Wasps are extremely strong, they only need to use a super strong jaw to bite a few times to kill a honey bee.
This hornet can be 8 times larger than a honeybee.
When the battle is long, some wasps will also die.
However, the number of dead wasps is insignificant,
the wasps still succeed in invading the honeycomb.
2. Hornets attacked another honeycomb:
Hornets are known to be extremely aggressive, with venom sufficient to kill people.
They are carnivorous insects,
hornet larvae will consume other insect carcasses brought by the adults to their nests,
but adults will eat mostly nectar or fruits that are high in sugar.
That means they eat meat when they were young,
and when they grow up, they become vegetarian.
Adult hornets also eat other insects, typically honeybee larvae,
but they mostly eat nectar and sugar.
This species of hornets is smaller in size than Asian giant hornets.
Its size is not much larger than that of the invaded bees. So it will be harder to kill the enemy.
After defeating all worker bees, they will enter the nest and eat the larvae,
which contain a lot of nutrition.
We can see the battle was fierce, and the hornets once again won.
The number of dead hornets is also available, but less.
3. However, giant hornets not only attack other bees, but also attack their fellow species.
This usually happens when the amount of food becomes scarce,
hornets are too hungry and decide to invade other hornet nests to eat larvae contained inside the nest.
This will also help reduce the food competition for them.
We see that the size of each side is almost the same,
so whichever is more crowded will win.
Invading hornets gathered all their forces to ambush the nest,
while the enemy members were unable to assemble their forces,
so their number were smaller than the invader's.
Invading hornets kill all owner hornets outside the nest.
Many hornets will gather to attack an opponent.
Hornets use a strong jaw and venom tail to attack.
Their jaws are strong, and they often try to take out their opponents by tearing their bodies.
To bite off the head or abdomen of the enemy.
We cannot distinguish each side, because their colors are so similar.
And only really know which side wins when the game is over.
Finally, the hornets who invaded won.
They began to go deep into the nest.
They went into the nourishment of female hornet larvae,
and the offspring that were about to become queen next year were killed and eaten.
The survival war is sometimes very cruel!
4. Spider wasps hunt spiders as food for ther larvae.
The spider will inject venom repeatedly until the spider is paralyzed.
Now I will say some facts of these wasps and how they used to catch spiders.
Wasps in the family Pompilidae are commonly called spider wasps, spider-hunting wasps, or pompilid wasps.
The family is cosmopolitan, with some 5,000 species in six subfamilies.
Nearly all species are solitary (with the exception of some group-nesting Ageniellini),
and most capture and paralyze prey.
Unlike many other families in the Aculeata,
essentially all wasps in this family are solitary (nests made by a single female).
Adult pompilids are nectar-feeding insects and feed on a variety of plants.
Depending on genus and species, pompilids capture a variety of spiders for their larvae to feed on,
covering nearly all free-living spider families,
though any given pompilid tends to attack only a limited diversity of spiders.
A female wasp searches the ground or vegetation for a spider,
and upon finding one, stings it, paralyzing the spider.
The targeted spider typically isn't able to kill the wasp, because the wasp can just fly out of reach,
It's kind of unfair in my opinion :))
so at best the spider fights fiercely to escape.
Tarantula hawks (Pepsini) do not attack when adult tarantulas are close to or in their burrows.
Instead, the wasps seek out adult males who have left their burrows in search of females to mate with.
In the open the wasp first uses its wings to beat air over the tarantula,
deceiving the tarantula into thinking that it being targeted by a large bird
so the tarantula reacts by curling up to appear smaller and less noticeable,
which in turn makes the tarantula defenseless against the wasp's attack.
We see a very cunning wasp.
Once the spider is paralyzed, a female pompilid makes a burrow
or flies or drags the spider to a previously made burrow.
Because of the large body size of their prey,
tarantula hawks usually will either construct burrows near the site of attack
or use the host's own burrow or tunnel.
Pompilids typically provide each of their larvae with a single prey/host,
which must be large enough to serve as its food source throughout its development.
After all, they are very smart insects
5. Emerald cockroach wasp stinging a cockroach and using it as a host for its larvae:
Cockroach is an insect famous for its good survival,
but there are many insects that can defeat it,
including one with an extremely strange attack method.
The emerald cockroach wasp or jewel wasp (Ampulex compressa) is a solitary wasp of the family Ampulicidae.
Cockroach wasp is an extremely annoying enemy for cockroaches.
This wasp is small but possessing powerful nerve venom paralyzes the brain of the cockroach.
Females after mating with males will look for cockroaches to inject parasitic eggs.
Female wasps of this species were reported to sting a cockroach twice, delivering venom.
The first sting injects venom to mildly and reversibly paralyze the front legs of its victim.
The second venomous sting at a precise spot in the victim's head,
and then the cockroach become sluggish and fail to show normal escape responses.
The wasp, which is too small to carry the roach, then leads the victim to the wasp's burrow,
by pulling one of the roach's antennae in a manner similar to a leash.
The cockroach is now paralyzed, so it moves only in the direction of the wasps.
Like Michonne and a walking dead.
In the burrow, the wasp will lay one or two white eggs,
about 2 mm long, between the roach's legs.
This time cockroaches will basically have a tragic ending.
The wasp's egg hatches after about 3 days.
The hatched larva lives and feeds for 4–5 days on the roach,
then chews its way into its abdomen and proceeds to live as an endoparasitoid.
Over a period of 8 days, the final-instar larva will consume the roach's internal organs,
finally killing its host, and enters the pupal stage inside a cocoon in the roach's body.
Eventually, the fully grown wasp emerges from the roach's body to begin its adult life.
These actions are quite similar to the way the Alien Xenomorph species used in the movie.
In confrontations with the wasps, cockroaches can defend themselves with strong kicks,
along with some other tactics to avoid tragic outcomes.
They tend to hit opponents in the head with spiked legs.
The survival rate of an adult cockroach without time to defend is only about 14%.
However, if a cockroach can use some kicks quickly,
the survival rate can be up to 63%.
So the content of the wasps battles is over.
